Specification of Letters Patent.

Patented Jan. 29, 1907.-

Application filed August 11, 1906- Serial No. 330.128-

To all /1 am if may concern:

Be it known that. I, Jonx F. APPLEBY, a citlzen of the United States, residlng at Chlcago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Cotton-Harvesting Machines, of which the following is a-full, clear, concise, and exactdescriptlon, reference bemg had to the accompanying drawings, forming a part of this specification. My invention relates to cotton pickin or harvesting machines, and has for its ob ect the provision of means for preventing the cottonicking fingers from gathering foreign materia such as sap, or moisture, that would im air the efficiency of the fingers.

n practicing my invention I employ a receptacle for material that is to be applied to the fingers for the purpose indicate this receptacle having an opening in a wall portion .thereof, which wall portion constitutes a duct through which. the material may be directed to the fingers. In the preferred embodiment of the invention the receptacle is placed in such a position that this ductor pipe portion is considerably removed from the fin ers, inwhich case I referably supplement t e same by an additional duct-or pi e portion in the form of a tube set into t e o ening in the receptacle. The material t at I prefer to employ for ap lication to the fingersis kerosene, and this erosene is desirably forced through the duct toward the fingers to form a spray, which reaches the space that the fingers'are to occupy when t ey are being treated to an application of the kerosene.

In the preferred embodiment of the invention the oil-receptacle is preferably so located that gravity is not relied upon to cause the oil to be'spray'ed, and I therefore desirably employ a pumpwhich will effect the forcible ennssion of the oil through the duct. The jet of oil is referably fan-sha ed in plan view, to which end the nozzle 0 the duct is In order that the stream of oil may be caused .to flowmtermittently only, I employ a device which intermittently shuts off the connection between the duct and the oil-suply, this mechanism being desirably operated by some rotating element of the machine operated by the traction-wheels thereof, and I broadly claim herein the mechanism for effecting the intermittent application of oil or other material to the fingers. I also provide means whereby the flow of oil through the duct may be totally discontinued when desn'ed. e v I will explain my invention-"more fully by reference to the accompanying drawings,

illustrating the preferred embodiment thereof, in which p c Figure 1 is a side elevation of soflmuch of the type of cotton-picln'ng machine, together with mechanism employed in association therewith, as is necessary to an understanding of the invention. Fig. 2 is a plan view of the nozzle of the pipe or duct through which oil is sprayed upon the fingers.

Like parts are indicated by similar characters of reference throughout the different figures.

Some of the mechanism shown in Fig. 1 of the drawings forms the subject-matter of m. United States Letters Patent N 0. 798,651 and dated. September 5, 1905; but I do not wish to be limited to the precise harvesting mechanism that I have illustrated.

In the drawings there is disclosed a plurality of picking-fin ers 1, that are mounted bodily in vertical p anes parallel with the line of travel ofthe harvester and to be rotated about its axis while picking cotton by mechanism fully disclosed in my aforesaid patent and which need not here be mentioned in detail.-

The picking-fingers are desirably tapered and serrated and the kerosene is desirably a plied to the entire surfaces of the fin ers it at are likely to contact with the bus es.

The oil finds passage through the pipe or duct 2, which is preferably provided with a fiattened nozzle, as indicated at 3, Fig. 2, wherebythe oil issues from the duct in a fanshaped spray that extends transversely of the machine. Where a pump-feed action is employed, the pipe 2 desirably extends downwardly into connection with the upper portion of the pump-barrel 3, anopenmg being afforded in this pumpbarrel, the ipe 2 being brought into communication wit said ope ning. The pump-barrel itself also constitutes a not portion, and the apertured bottom 4 of the pump-barrel alsoconstitutes a duct portion, the oil in the tank 5 being conve ed through said duct portions and the nozzle'3 whenever the will ap ear.

A va ve 6 is provided for opening and clospump set into operation, as

each adapted ing the a erture in the bottom 4 of the pump-- barrel, t is valve mission of oil from the c amber 5 whenever the piston 7 of t epump is raised to eject oil through the duct 2. It need hardly be said that when the piston is depressed the valve 6 is closed and that said piston is itself rovided with a valve 8 that permits the oi to rise above the piston as the piston descends.

15 avencv, desirably in tion of oil through The piston is intermittently operated by some moving part of the machinery of the harvester, and I have for sake of convenience selected as such amoving part one of the operating-gears 9, provided uponwhich is a suitable actuating the form of a lurality of rollers 10, distri uted at equal istances along the periphery of the gear y A horizontal rod 11, disposed in suitable guides 12, is provided with a foot 13, that is normally pressed toward the gear 9 by means of some spring mechanismas, for example, the spring 13-said spring exerting its action upon sai rod 11 through the agency of the upright arm of a bell-crank 14:, that engages an angular addition 15 to the rod 11. The

other end ofsaid bell-crank has cross-head connection with the stem or shaft of the piston 7. The spring 13, which has a stationary abutment at its lower end, not onl operates to press the foot 13 toward the rol ers 10,

but also operates to move the piston downward as each roller disengages itself from the foot. When, however, a roller engages itself with the foot, the spring 13 is compressed the action of the rod 11 and associate parts, said rod then being moved by the engaging roller toward the bell-crank 14 to effect the elevation of the piston, and thereby the ejecthe spout or nozzle 3. In this way the material that is to be applied to the fin ers is caused to be fed intermittently, an this I consider to be a very imgortant characteristic of the invention herein isclosed, though I do not Wish to be limited thereto in all embodiments of the invention. Where it is desired to throw the sprinkling apparatus out of service alto ether, the angular extension 15 upon the r 11 may be rotatably mounted upon said rod 11, so that it may be swung to one side to have its free end out of the path of the upright arm of'the belloil may be permitted the cover 16, from which the pil may drop to enable the element crank lever, the engagement between the parts 11 and 15 being with sufficient friction to be maintained in any position to which it is swung.

. The oil is not only directly cast upon the fingers through the pipe 2, but a part of the to strike the inside of onto the fingers. v

'hile I have herein shown pumping mechanism for forcibly ejecting the material that is to be applied to the fingers, I do not wish to be limited to a mechanism by which such forcible ejection is had.

6 bein raised for theaddeparting from the spirit of said material throng In the claims I speak of dropping or otherwise applying oil or other suitable material upon the cotton picking fingers, meaning thereby that said 011 or other material is ap- 311911 to the portions of the fingers that proect into the cotton-plants.

' It is obvious that changes may be made in the embodiment -of the invention herein shown and particularly described without of the invention, and I do not, therefore, wish to be limited to the precise construction shown; but,

Having thus described my invention,. I claim as new and desire to secure by Letters Patent- 1. A- cotton-picking machine including cotton-picking fingers, and a'spraying device for aplp ying material to the fingers.
